Offering free Wi-Fi hotspots is just one of several improvements Michigan International Speedway will be offering those who attend the June and August races this year.

MIS has invested more than $75 million into various capital improvement projects across its 1,400-acre campus since 2006, according to a news release. Track president Roger Curtis said the improvements — particularly the addition of Wi-Fi hotspots — will enhance the visit of those who attend.

"Nothing can beat the live experiences, the sights, the feel and the smell of a race," Curtis said in a statement. "Now we've added part of the technology element that fans are accustomed to at home. Like viewers at home, fans at MIS will now be able to check their NASCAR fantasy league scores, tweet, Facebook and text."

The free Wi-Fi will be available to all cellphone carriers, Curtis said.

The track at 12626 U.S. 12 will also have in-seat service to allow guests to purchase snacks or beverages from their seat.

Vendors will have the items printed on their shirts with prices. Guests can simply point to what food and beverage they want. The service will start two hours prior to the race and will end with about 25 laps remaining.

Infield campers will see new restroom facilities in 2013. In addition, three restroom facilities in the center grandstand will also be demolished and reconstructed, while other restroom facilities will be refurbished.

The RV campground in Turn 3 is also being expanded by 10 sites.

The MISCamping.com Tree Farm Campground is also expanding with the addition of 26 new sites. All of the new campsites will be along the tree line. The campground is behind the Turn 3 grandstands off of M-50.
